Pwm Low-side Driver 1.5a And 3a For Solenoids, Coils, Valves, Heaters, And Lamps

  The DRV103 is a low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, RELAYs actuators, Motors and positioners. The DRV103 is also ideal for driving thermal devices such as heaters, coolers, and lamps. PWM operation conserves power and reduces heat rise, resulting in higher reliability. In addition, adjustable PWM allows fine control of the power delivered to the load. DC-to-PWM output delay time and Oscillator frequency are also externally adjustable. The DRV103 can be set to provide a strong initial closure, automatically switching to a ?soft? hold mode for power savings. A Resistor analog voltage, or Digital-to-Analog (D/A) converter can control the duty cycle. An output OK flag indicates when thermal shutdown or over current occurs. Two packages provide a choice of output current: 1.5A (SO-8) or 3A (PowerPAD? SO-8 with exposed metal heat sink). The DRV103 is specified for ?40?C to +85?C.
